Standard vs Itemized Deduction: Important Catches Part 2

Standard Deduction: The Simple Choice

The standard deduction is a flat dollar amount that reduces your taxable income. It is essentially an automatic deduction available to all taxpayers. The amount varies by filing status and is adjusted annually for inflation. For most taxpayers, the standard deduction is the simpler and often more beneficial choice.

Itemized Deductions: When Your Expenses Add Up

Itemizing means listing out specific qualifying expenses that exceed the standard deduction amount. Common itemized deductions include medical expenses (above a percentage of AGI), state and local income or sales taxes, property taxes, mortgage interest, and charitable donations. Casualty and theft losses in federally declared disaster areas may also qualify.

You must choose between the standard deduction and itemizing — you cannot claim both. The rational approach is to calculate your total itemized deductions and compare them to the standard deduction, then choose whichever is larger.

Making the Right Choice

For a single filer, if your itemized deductions (mortgage interest, property taxes, state taxes, charitable donations, etc.) total more than the standard deduction amount, itemizing saves you more money. If your itemized deductions total less, take the standard deduction.

Since the Tax Cuts and Jobs Act significantly increased the standard deduction, fewer taxpayers benefit from itemizing. However, homeowners with large mortgages, taxpayers in high-tax states, and those making substantial charitable contributions often still benefit from itemizing.
